<a class="xref" href="analysis-standard-analyzer.html" title="Standard Analyzer">Standard Analyzer</a>
</span>
</dt>
<dd>

by the Unicode Text Segmentation algorithm. It removes most punctuation,
lowercases terms, and supports removing stop words.

<span class="term">
<a class="xref" href="analysis-simple-analyzer.html" title="Simple Analyzer">Simple Analyzer</a>
</span>
</dt>
<dd>
The <code class="literal">simple</code> analyzer divides text into terms whenever it encounters a
character which is not a letter.  It lowercases all terms.
</dd>
<dt>
<span class="term">
<a class="xref" href="analysis-whitespace-analyzer.html" title="Whitespace Analyzer">Whitespace Analyzer</a>
</span>
</dt>
<dd>

<a class="xref" href="analysis-keyword-analyzer.html" title="Keyword Analyzer">Keyword Analyzer</a>
</span>
</dt>
<dd>
The <code class="literal">keyword</code> analyzer is a “noop” analyzer that accepts whatever text it is
given and outputs the exact same text as a single term.
</dd>
<dt>
<span class="term">
<a class="xref" href="analysis-pattern-analyzer.html" title="Pattern Analyzer">Pattern Analyzer</a>
</span>
</dt>
<dd>
The <code class="literal">pattern</code> analyzer uses a regular expression to split the text into terms.

<span class="term">
<a class="xref" href="analysis-lang-analyzer.html" title="Language Analyzers">Language Analyzers</a>
</span>
</dt>

<span class="term">
<a class="xref" href="analysis-fingerprint-analyzer.html" title="Fingerprint Analyzer">Fingerprint Analyzer</a>

<p>If you do not find an analyzer suitable for your needs, you can create a
